Yes, human visual perception exists along a spectrum of temporal, spatial, and chromatic resolution that varies from person to person — I’ve even met some people who can’t perceive the difference between 30hz and 120hz, while to me and most people I know, the difference between 60hz and 120hz is enormous.
So you could make the same argument against high DPI displays, superior peak screen brightness, enormously better contrast ratio, color gamut, etc. Also speaker quality, keyboard quality, trackpad quality, etc.
Where does this argument end? Do you propose we regress to 60hz 1080p displays with brightness, contrast, and viewing angles that are abysmal by modern standards? Or is the claim that the MacBook Air’s current screen is the perfect “sweet spot” beyond which >99% of people can’t tell the difference?
I think the market data alone disproves this pretty conclusively. Clearly a significant enough percentage of the population cares enough about image quality to vote with their wallets so much so that enormous hardware industries continue to invest billions towards make any incremental progress in advancing the technology here.
To be fair, I think there’s strong data to support that modern “retina”-grade DPI is good enough for >99% of people. And you can argue that XDR/HDR is not applicable/useful for coding or other tasks outside of photo/video viewing/editing (though for the latter it is enormously noticeable and not even remotely approaching human visual limits yet). But there’s plenty of people who find refresh rate differences extremely noticeable (usually up to at least 120hz), and I think almost anyone can easily notice moderate differences in contrast ratio and max brightness in a brightly lit room.

- VincentEvans 2y agoLol, reminds me of audiophile discussions when most people listen to youtube streaming a recompressed version of an mp3 someone uploaded.
- toxik 2y agoIt’s not imagined though, I use my partner’s phone sometimes and every time I used it I thought it was broken because the UI jitter was so jarring at 60Hz. Actually I’m still not convinced her phone isn’t broken. Also her flashlight resets to the lowest brightness EVERY time it’s cycled.
- crazygringo 2y ago> because the UI jitter was so jarring at 60Hz See this is what confuses me. If the UI jitter on their phone was "so jarring", it's not because it's 60 Hz. It's because the phone's CPU isn't keeping up. Like, nobody watches a video filmed at 60 fps and then watches their favorite TV show or a motion picture at 24 fps and says "the jitter was so jarring". And that's at less than half the rate we're even talking about! Similarly, even if you can tell the difference between 60 and 120 Hz, it's not jarring. It's not jittery. It's pretty subtle, honestly. You can notice it if you're paying attention, but you'd never in a million years call it "jarring". I think a lot of people might be confusing 60 Hz with jittery UX that has nothing to do with the display refresh rate. Just because the display operates at a higher refresh rate doesn't mean the CPU is actually refreshing the interface at that rate. And with certain apps or with whatever happening in the background, it isn't.

And that's at less than half the rate we're even talking about! Those have motion blur. > Similarly, even if you can tell the difference between 60 and 120 Hz I don't know why you're phrasing this so oddly doubtful? Being able to tell the difference between 60hz and 120hz is hardly uncommon. It's quite a large difference, and this is quite well studied.
